RACK FOR DISHWASHIN'G MACHINES.

Application filed September 25, 1923, Serial No. 664,762, and in CanadaAugust 2, 1923.

The invention relates to improvements in once indicate correspondingparts in the sevracks for dish washing machines and an oral figures.object of the invention is to provide a rack The dish washing rack isformed preferawhich will hold a considerable quantity of bly from wirein the form of an open frame dishes of varying sizes and which isdesigned work.

The dishes customarily washed in a dish washing machine vary, but thesizes are usually regular. that is to say, there are large. small andintermediate plates 19, 20 and 21, such as dinner plates, saucers andtea plates. The large plates are stacked in the outer part of the rack,small plates in the inner part of therack and intermediate plates in theintermediate part of the rack and in all instances the lower edge ofeach plate rests in the lower end of two pockets and has the backthereot engaging the adjoining vertical loop or arm 18. According to thearrangement provided the inner, outer and intermediate sets of platestake an inclined position. as shown in Figure 1, and here it will beobserved that their edges are approximately parallel and they have theirupper edges tilted outwardly. I wish particularly to point out that theshape of the pockets 12 and the weight of the dishes thus effectivelyprevent the inserted dishes from changing their relative position whenthe machine is in use.

As there is usually a certain amount of solid material adhering to theplates which is subsequently washed oft, it is desirable to collectthis. if possible, so that it may not remain lodged on the plates afterthe dishes have been washed. 1 accomplish this by placing'in the rack astrainer 22 which is positioned more or less tangential to the innerring-10 and has the open side or mouth 23 thereof in the vertical planeand directed toward the spiralling flow of water coming up through therack. The strainer is supported in the following manner: it is providedat the side with two outstanding vertically extending wings 24 and 25and these wings are adapted to enter vertically extending opposing guideslots 26 and 27 appearing between upwardly extending pairs of spacedguide bars 28 and 29 carried by the rods 11- The upper ends of the guidebars are laterally deflected as indicated at 30 and 31, to prevent thewings from rising when the strainer is subjected to the pressure of thewater.

The rack is suitably supported within the casing 5 by angle brackets 32attached to the sides of the casing.

In order that the value of the rack may be better appreciated I haveshown the propeller or double winged blade 33 which I use in the bottomof the casing, the blade being carried by a vertically disposed suitablymounted shaft 34 driven by a belt 35 from the motor 36. This blade anddriving mech anism forms the subject matter of a separate patentapplication and accordingly the same are not herein described in detail.

When the machine is in use the propeller operates at comparatively highspeed and thrusts the water originally placed in the lower part of thecasing in an upward and outward direction, the water spirals as itrises. The general direction of travel of the water is upwardly betweenthe plates and the plates in no way battle the flow of water.Accordingly they are effectively washed on both sides and the velocityof the passing water is not abruptly killed by the plates- In thisconnection I might point out that the plates are suspended in a positionsubstantially at right angles to the upper edges of the blades. Theforks, knives and spoons are effectively washed by av comparatively finespray appearing in the central part of the tank and any foreign materialsuspended in the water is caught by the strainer which is opposed to thespiral direction of travel of the water and accordingly in the time thatit takes to wash the dishes has suflicient time to catch practically allof the solid material contained in the tank.

What I claim as my invention is:

1. A plate supporting rack having spaced, upwardly inclining, platesupporting rods and with the rods bent to present opposin pocketscontained in vertical planes and adapted to receive the lower edges ofthe standing plates with the lower edge of each plate resting in twoadjacent pockets and having the rod portions forming the pocketsinclined to cant the upper edges of the plates in a direction away fromthe upper ends of the rods and upstanding stationary arms interposedbetween adjacent rods and eninclining, radiating rods, the rods beingbent to present opposing pockets contained respectively in the verticalplanes containing the rods and adapted to receive the lower edges ofstanding, out canted plates with the lower edgev of each plate restingin two adjacent pockets and upstanding stationary arms interposedbetween adjacent rods and engaging the upper edges of the several platesand supporting them in the out'canted position.

3. A cylindrical plate supporting rack having thebottom thereof closedby radially extending and upwardlv inclining, spaced, plate supportingrods, the rods being similarly bent at intervals to provide a pluralityof opposing, similar. acute angled pockets contained in the verticalplanes containing the rods and adapted to receive and support the loweredges "of out canted plates and stationary upstanding arms interposedbetween adjacent rods and engaging the upper edges of the out cantedplates and supporting the same in such position- 4. A cylindrical platesupporting rack having the hottom closed by upwardly inclining, radiallydisposed. suitably spaced, plate supporting rods and having the rodsbent to provide downwardly extending, aeule angled pockets and havingthe apiees of the poekets pointing inwardly toward the axis of the\'lindri(.-al rack, the opposing pockets of ad jaeent rods being adapted10 to receive and support the lower edge of a plate and hold the platein an out canted position and upstanding stationary arms interposedbetween adjacent rods and engageahle with the upper ed es of the severalplates and supporting canted position.
